Verifying the no-hair property of massive compact objects with intermediate-mass-ratio inspirals in advanced gravit...

The perihelion advance of the orbit of Mercury has long been one of the observational cornerstones for testing General Relativity (G.R.). The main goal of this paper is to discuss how, presently, observational and theoretical constraints may challenge Einstein’s theory of gravitation characterized by β = γ = 1. To achieve this purpose, we will first recall the experimental constraints upon the ...

1550-7998=20 Numerical simulations of binary neutron stars by Wilson, Mathews, and Marronetti indicated that neutron stars that are stable in isolation can be made to collapse to black holes when placed in a binary. This claim was surprising as it ran counter to the Newtonian expectation that a neutron star in a binary should be more stable, not less. After correcting an error found by Flanagan...

Abstract The regularization and renormalization of the radiative mass-type quadrupole moment inspiralling compact binaries (without spins) is investigated at fourth post-Newtonian (4PN) approximation general relativity. As clear from conservative 4PN equations motion, a dimensional has to be implemented in order properly treat non-linear interactions experienced by gravitational waves during th...

Introduction: Cassini radio science data indicates that Titan is nearly in hydrostatic equilibrium [1]. We have used thermal models [2] and hydrostatic equilibrium theory [3] to derive interior models of Titan. We show as the measurement of the principal quadrupole gravitational coefficient C22 from the Radio Doppler data from Cassini spacecraft will improve our knowledge of the interior struct...

In this paper, we introduce the octopole moment of the light distribution in galaxies as a probe of the weak lensing shear field. While traditional ellipticity estimates of the local shear derived from the quadrupole moment are limited by the width of the intrinsic ellipticity distribution of background galaxies, the dispersion in the intrinsic octopole distribution is expected to be much small...

We investigate the properties of a closed-form analytic solution recently found by Manko et al. (2000b) for the exterior spacetime of rapidly rotating neutron stars. For selected equations of state we numerically solve the full Einstein equations to determine the neutron star spacetime along constant rest mass sequences. The analytic solution is then matched to the numerical solutions by imposi...

We use a " hybrid " method, mixing variationally-determined triaxial nuclear Slater determinants, to calculate the response of 73 Ge to hypothetical dark-matter particles such as neutralinos. The method is a hybrid in that rota-tional invariance is approximately restored prior to variation and then fully restored before the mixing of intrinsic states. We discuss such features of 73 Ge as shape ...

The Kerr solution is generated from the Schwarzschild solution by a simple combination of real global coordinate transformations and of invariance transformations acting on the space of stationary solutions of the Einstein–Maxwell equations. The same transformation can be used to generate a spinning field configuration from any static axisymmetric configuration. We illustrate this by generating...
